any  technical  trading
strategies revolve around
the assumption that mar-
kets will hover within a

given range — and with good rea-
son.  Seventy  percent  of  the  time
markets will bounce back and forth
between support and resistance lev-
els, or fluctuate randomly. The rest
of the time, market behavior is char-
acterized by persistent price moves
— trends — that shatter support and
resistance levels. 

Although these basic probabilities

work  against  traders  who  try  to
exploit trends, the potential rewards
can be worth the risk. It is possible to
increase your ability to capitalize on
t rends  by  locating  trend  signals,
identifying  specific  entry  points
within the trend and using risk man-
agement techniques to limit losses. 

The  following  sections  will

explain how a trading system based
on these concepts works especially
well in the foreign exchange (Forex),
or  curre n c y,  market,  particularly
with the “major” currencies — the
U.S.  dollar,  Euro,  Japanese  yen,
British 

pound, 

Swiss 

franc,

Canadian dollar and Australian dol-
lar.  More than 85 percent of transac-
tions in the $1 trillion per day Forex

market involve the majors. 

The strategy uses two charts with differ-

ent time periods (10-minute and hourly),
along with two technical indicators: a
200-bar moving average and a 14-bar
slow stochastic study (see “Stochastic

Trends may be rarer than trading ranges, but that 
doesn’t mean they can’t be traded. This strategy 
uses two time frames to identify the trend, an 
overbought-oversold indicator to pinpoint entry and 
a trailing stop to protect gains on profitable trades.

refresher,” right). 

Step 1: Identify a trend. Compare the

moving averages on the 10-minute and
hourly charts. A trend is in effect when
price is consistently above/below the
moving averages on both charts. 

Step 2: Pinpoint entry. Once you’ve

identified a trend, look for the following
two conditions at the same time on the
10-minute chart: 1) the market is no
more than 20 points above (to buy) or 20
points below (to sell) the moving aver-
age; and 2) the fast stochastic line cross-
es above the slow stochastic line below
20 (to buy) or crosses below the slow
stochastic line above 80 (to sell). 

These conditions indicate: 1) the cur-

rency  is  currently  in  a  short-term
uptrend or downtrend; and 2) the cur-
rency has paused or pulled back (reflect-
ed by the higher low stochastic reading
and the fact that price is within 20 points
of the moving average) and is poised to
turn (because the fast stochastic line is
crossing back above or below the slow
line).

Step 3: Ride the trend. Set a trailing

stop after the initial trade entry. On a
long position, enter a stop-loss order 10
points  below  the  200-period  moving
average on the 10-minute chart. In the
case of a short position, place the initial
stop 10 points above this moving aver-
age. As the trade goes in your favor, raise
(for a long trade) or lower (for a short
trade) the stop to protect profits. For
simplicity’s sake, the following exam-
ples use a trailing stop 25 points from
each new top or bottom. The charts in
the next section illustrate the application
of this strategy in two currency pairs.

The  first  example  took  place  in  the
E u ro c u r rency-dollar  (EUR/USD)  cur-
rency pair during the fourth week of
June 2002. (For those unfamiliar with
currency quoting and charting conven-
tions, see “Quoting currencies,” p. xx.)

First,  compare  the  hourly  and  10-

minute EUR/USD charts. Look for a
time when price is above the 200-period
moving averages on both charts. On the
hourly chart (Figure 1, opposite page),
the fact that price is almost exclusively

above  the  200-hour  moving  average
indicates a persistent uptrend. On the
10-minute chart (Figure 2, top left), price
moves (and remains above) the moving

Stochastic refresher

The stochastic oscillator consists of two lines: %K and a moving average of

%K called %D. 

The basic stochastic calculation compares the most recent close to the price

range (high of the range - low of the range) over a particular period. A basic
five-bar stochastic calculation is the difference between the most recent bar’s
close and the lowest low of the last five days divided by the difference
between the highest high and the lowest low of the last five days. The result
is multiplied by 100. The formula for this calculation, which is %K, is:

%K = 100*{(C

t

-L

n

)/(H

n

-L

n

)}

where

C

t

= the most recent bar’s closing price

L

n

= the lowest price of the most recent bars

H

n

= the highest price of the most recent bars 

(for a stochastic calculated on daily bars, the default is five days)

The second line, %D, is simply a three-period moving average of %K: 

average(%K,3)

Because this basic “fast” stochastic calculation is very volatile, an addition-

ally smoothed version of the indicator, where the original %D line becomes a
new “slow” %K line and a three-period average of this line becomes the “slow”
%D line, is more commonly used.

The stochastic can be made to reflect longer- or shorter-term price move-

ment and to be less or more sensitive to small price fluctuations by increasing
or decreasing the number of bars used to calculate %K and/or increasing or
decreasing the length of the moving average used to calculate %D. For exam-
ple, a stochastic using a 10-bar %K and a three-bar moving average for %D [sto-
chastic(10,3)] would be shorter-term and more sensitive than a stochastic
using a 20-bar %K and a five-bar moving average for %D [stochastic(20,5)].

average in the last third of the
chart. The next step is to pin-
point the entry zone — when the
market is within 20 points of the

moving  average  on  the  10-
minute chart and the stochastic
lines cross. 

The range between 1 p.m. and

midnight on June 27 meets these
re q u i rements.  The  entry  point
occurs when the fast stochastic
crosses above the slow stochastic
when the indicator is below 20. A
long position is entered at .9883
around 8 p.m., with an accompa-
nying  stop-loss  at  .9858  (10
points below the 200-bar moving
average value of .9868). The stop
is  then  trailed  upward  as  the
market makes new peaks. The
EUR/USD tops out at .9992, so
the  stop  scaled  up  to  .9967,
where the position was closed
for an 84-point ($840) gain.

Price is also above the 200-bar moving average in the final third of the 10-minute

line crosses above the slow line (a sign of renewed upside momentum) when the 
indicator is below 20 near 8 p.m.

Also, price was within 20 points of the

trade  was  opened  around  5  p.m.  at

119.57  when  the  fast  stochastic  line
crossed below the slow stochastic line
when the indicator was above 80.

The trade was protected with a

stop-loss order at 119.86. In this
case, the stop remained intact until
the following day, when USD/JPY
began to decline. After trailing the
stop down as the market contin-
ued to decline, profits were taken
at 118.58 (25 points off the 118.33
low), for a gain of 99 points.

Quoting currencies

B

ecause currencies are quoted in a different manner than equities, reading a
foreign exchange quote may seem a bit confusing at first. However, it’s real-
ly quite simple if you remember two things: 1) The first currency listed first

is the base currency and 2) the value of the base currency is always 1.

For example, if you see a quote of USD/CAD 1.54825, that means that one U.S.

dollar is equal to 1.54825 Canadian dollars. Likewise, USD/JPY 122.01 shows that one
U.S. dollar is equal to 122.01 Japanese yen.

In every trade involving the U.S. dollar, the dollar will be the base currency, with

three exceptions — the British pound (GBP), the Australian dollar (AUS) and the
European currency unit, or Euro (EUR). In these cases, you might see a quote such
as GBP/USD 1.4366, meaning that one British pound equals 1.4366 U.S. dollars.

Whenever the U.S. dollar is the base unit and a currency quote goes up, it means

the dollar has appreciated in value and the other currency has weakened. If the
USD/JPY quote we previously mentioned increases to 123.01, the dollar is stronger
because it will now buy more yen than before.

However, in the three instances where the U.S. dollar is not the base rate, a rising quote means a weakening dollar, as

it now takes more U.S. dollars to equal one pound, Euro or Australian dollar.

In other words, if a currency quote goes higher, that increases the value of the base currency. A lower quote means the

base currency is weakening.

Trades that do not involve the U.S. dollar are called cross rates, but the premise is the same. A quote of GBP/CHF 2.4577

signifies that one British pound is equal to 2.4577 Swiss francs.
